Graphics

Use built-in include_graphics function in knitr package to control size and scale of images.

Equations

Use LaTeX style code to make inline and block equations.
\(A = \pi*r^{2}\) \[A = \pi*r^{2}\]

Tables

Here is an ugly ass table. Don’t forget 2 spaces after each line:

Table Header	Second Header	Third Header
Table Cell	Cell (1, 2)	Cell (1, 3)
Cell (2, 1)	Cell (2, 2)	Cell (2, 3)

Here is a much nicer table.

knitr::kable(summary(cars))

	speed	dist
	Min. : 4.0	Min. : 2.00
	1st Qu.:12.0	1st Qu.: 26.00
	Median :15.0	Median : 36.00
	Mean :15.4	Mean : 42.98
	3rd Qu.:19.0	3rd Qu.: 56.00
	Max. :25.0	Max. :120.00
